I came from other forums here when I got my sg2 and I have to say the people here are the worst people on xda...every other phone I have used and flashed had so much support and no criticising....when I had my hd2 people bent over backwards to help and didn't knock you for everything you try to do....I feel you man and it sux because I'm in contract with this phone until next March...I just had a thread closed because I asked a simple request and people jumped down my throat....

Hope ayysir will continue his work here ,I truly appreciate what he does , and in my opinion is one of the best devs here. Don't mind the bad things other people say , they just don't have anything better to do. He's one of the reasons why I don't feel this phone is outdated , so he's doing a lot of us a favor but it seems that some people don't realize that

I find it redundant and quite ignorant to find everyone in the last couple of pages keep repeating what each other member has said. If the man made his mind up, what makes you think your kind words will help him return? Sure, it shows that some of us care and the others are neutral when it comes to this predicament, but is it really necessary for everyone to blatantly spit out their own version of pity toward ayysir? The most you guys can do to support him is for his testers to report bugs and not slack. I admit, I'm a hypocrite because I failed to do these things, but input from the community on what is working/not working is going to show ayysir your determination towards this kernel, because without him you will all be crushed. Please, save your pity talk and stop spamming this thread with it (this includes stupid 1 word remarks like "+1" or "I agree". If you're going to thank or support what someone said, there is a button for it).

Re: [KERNEL][JB-4.1/4.2][2/25/13] All-Star Devs Kernel RC2 Weekly

I appreciate all the love from everyone but Shmi117 is correct in a sense with above statement.

This is how my last two weeks went:

My paypal was hacked into. Someone made a 200 purchase on my account while I was asleep and cause me to have a negative 160 balance in paypal. Also lost some money from my actual bank account as a result after a few days of trying to resolve that issue. Had to change all my passwords and monitor my accounts now. Discouraged because I highly suspect it was a xda member but I won't point fingers.

2nd having tough time with my sgs3 builds ever since 4.2.2. Dropped. It won't load onto any rom except liquid smooth.

3rd put Nexus 7 dev on back burner to promptly fix errors for sgs2 builds. If I didn't I would be posting a Nexus 7 build this week and be on mako development atm

So things have been shatty

Ok people, what is going on here........ has the full moon sucked out all the common sense in this thread?........ Pay Attention:

1st thing .... if you cannot post on topic .....DO NOT POST

IF you cannot post respectfully............DO NOT POST

IF you cannot follow the rules for XDA and/or are just way to adolescent to be kind and considerate then

.....DO NOT POST and do not participate in XDA

There is no reason for all this poor behavior toward this Dev , or any Dev. They make something out of their love and curiosity for Improving their phone experience and share it freely.........be thankful.....

If you have an issue then show us your skills and make a rom and share it with us......... oh yeah..........most of you do not have the skills that is why you have to use others work......... so if that is the case show some respect....... or make your own...

All the cry baby and whining BS is just crazy not to mention a WASTE of everyone's time especially for those like myself who hang in the shadows to learn unless I have something important to say.

On your phone in terminal editor type:

su

Terminal editor will request root access, choose allow. You will change from $ to #. Type (or copy/paste):

cat /proc/wakelocks > wakelocks.txt

Wakelocks.txt will appear at the root of your system. If you want to place it in a specific path, add that before wakelocks.txt. e.x.:

cat /proc/wakelocks > /sdcard0/wakelocks.txt

Please note the space after cat. It MUST be there.

If using adb it will be COMPLETELY different.

adb pull "/proc/wakelocks" "C:/Users/Chris/Desktop"

Of course... Change Chris to your username...

Use the 4.1.2 version. Yes it will improve performance and battery life. I believe USB fast charge is included. If you want great battery experiment with CPU gov/ io scheduler. I use BFQ, abyssplug, and under clock at 1026.

Had avg 8 days standby time when not using my phone yesterday.

Other battery savers:

Lower screen brightness.

Use 2g instead of 4g when you don't need massive speed.

Make sure apps aren't wake locking your device.
